Re: How can I type the characters printed in green colour on the keyboard of Acer aspire switch 10?
I've now tried. Using the Fn-key would only type the characters printed in blue. The backslash was printed in green, as is the danish ae and 0-slash (ö). Explaining the problem to my wife, she wanted to give it a go. And to my surprise solved it in under one minute. I had missed that the backslash WAS ALSO printed in white on the same key as + and ? so to be able to type it, all I have to do is to hold the Alt-Gr key down while pressing this key. Stupid of me to don't see it the first time around.
Going back to the original question about the characters printed in Green, I have come to the conclusion that these are for "converting" the keyboard to a Danish country-specific layout by specifying that keyboard-layout in Windows settings. Similarly, there are some characters printed in Red. I assume these are for Norwegian.
This type of complexity is what you get when the manufacturers want to reduce the country-variants to as few as possible, I suppose.
So all is good and well here 
For reference, I am attaching a pic of my keyboard
Just to confirm, hgpuke is right on track. The green and red text is setup to be a reference if you're on a different keyboard layout than the original language. This is used in many countries where there are multiple common languages. In Canada, we use English as the default and provide a French alternative with the green layout. Here's an article to help with changing the keyboard layout on Windows 8.1.
